Sometimes it pays to meet the person you want to work on your boat.
Are they experienced? Do they cut corners?
Don't let money be the only factor in guiding your choices.
Maybe You don’t need a valve job.

The same” bargain” mechanic then diagnosed “a valve problem” and quickly said it outside his skill set. We discovered the oil reservoir had been overfilled by about two quarts and was floating the lifters. A less than reputable guy would have taken it apart, found nothing, sent the cylinder heads out to be reworked, maybe even install a new set of lifters in it and handed the customer a $1,500 repair bill. He would probably think he had somehow fixed the problem, because he would have had to change the oil in the process.
Poor performance does not automatically mean you need a tune-up or a new prop.
There are many overlooked contributors to poor performance. I look for simple answers first, like water in the bilge. Undiscovered water can seriously sap a boat’s ability to get onto plane or reach top speed. Another culprit can be bottom growth. An incorrect prop can seriously hinder a boat’s performance. But many shops incorrectly diagnose a prop change when in reality the boat had grown heavier from the water, and bottom growth. Also the amount of equipment being stored on board can contribute. Multiple tune-ups are often thrown at engines that are simply tired and in need of a reconditioning
